A double convex lens has a focal length of \(25\) cm. The radius of curvature of one of the surfaces is double of the other. What would be the radii if the refractive index of the material of the lens is \(1.5?\)
1. \(100\) cm, \(50\) cm
2. \(25\) cm, \(50\) cm
3. \(18.75\) cm, \(37.5\) cm
4. \(50\) cm, \(100\) cm
1. | virtual, upright, height \(=0.5\) cm |
2. | real, inverted, height \(=4\) cm |
3. | real, inverted, height \(=1\) cm |
4. | virtual, upright, height \(=1\) cm |
